BED OR PILLOW.

SPECIFICATION forming part of Letters Patent No. 277,979, dated May 22,1883.

' I Application filed December 12, 1882. (No model?) To all whom it mayconcern:

Be it known that we, EMANUEL BLOOHMAN and GEORGE E. EVANS, of the cityand county of San Francisco, State of California, have invented anImproved Bed or Pillow; and we hereby declare the following to be afull, clear, andexact description thereof.

Our invention relates to certain improvements in pillows for beds or formattresses and similar articles; and it consists of an exterior bodymade of any flexible air-tight material, so that it may be inflated, andhaving a series of elastic flexible braces uniting its sides and top andbottom to hold them in place and to equalize the expansion andcontraction, as shown in a former patent granted to us. In combinationwith these flexible braces we employ rings, loops, or guides at thepoints where the braces approach or cross each other, and attach them toone set, so that the others may pass through the loops, and the wholefabric will thus be steadied, as will be more fully explained byreference to the accompanying drawings, in which- Figure 1 is aperspective view of our invention. Fig. 2 is a section.

When made in the form ofa pillow, as shown in our present drawings, thesides, top, and bottom merge or curve into each'other; but when madelarger, to form a mattress, the sides and ends will be somewhat moreVertical and the top and bottom slightly flattened; but the constructionis similar in each case.

A is a pillow or mattress, which is made of any suitable imperviousmaterial. A lockingnozzle, B, is fitted into one side or end, by whichthe pillow may be inflated with air and the opening tightly closed. Inorder to retain the sides and top in the proper positions and resist theexpansive force of the air, as well as to equalize the strains due tothe varying pressure and the mobile quality of the confined air,flexible tension braces or stays Gextend across from side to side andend to end, and also from top to bottom, as shown. These braces may alsobe elastic, if desired.

each other.

D D are rings, loops, or guides, which are fixed to the braces at pointswhere the longitudinal and transverse or Vertical braces cross If thebraces are not elastic, these guides may be made elastic; or the bracesmay be elastic, if desired. The guides D are fixed to the longitudinalbraces at intervals and at such points that the transverse braces willpass through them. These may also be fixed tothe intersecting verticalbraces, and will thus serve to prevent any swaying movements. Theguides, which are fixed to the transverse braces or stays in the samemanner, have the longitudinal braces passing through them, and each ofthese sets of guides may also have stays, which connect them with thetop and bottom of the pillow, thus making the whole very rigid as far asside or end movements are concerned, but yielding and flexiblevertically.

We are aware that air-tight pillows and beds have been formed andsecured by means of a series of eyelets; but such we do not claim as ourinvention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-- 1. A pillow'or bed composed of imperviousflexible material, with the longitudinal and transverse stays G, incombination with the rings or guides D at their points of intersection,substantially as herein described.

2. A pillow or bed composed of impervious flexible material, with ameans for inflation, and having the longitudinal and transverse stays Oand the rings D, in combination with the vertical stays and ringsintersecting the horizontal ones, substantially as herein described.

In witness whereof we hereunto set our hands.
